Should image augmentation be applied before or after image resizing?
As it is told in PIL documentation
It uses some filters to resize images.And those filters are explained here
uses mostly numerical methods as I see. So it is approximating the image data input. Which means you are right about data loss. But here might be the question would it change the data so much If it is done after augmentation or before?
Since in numerical methodic approaches the more values means more valid approximation in general.
So it might be beneficial to augment and then resize.
But one should look for its real answer. Mine is just a thought experiment. You will get better proven answers
